VALVE MECHANISM FORCQIN-,CONTROLLED GAS-VENDING MACHINES.

SPECIFICATION forming part of Letters 'Patentllfd 704,950, dated July 15, 1902. Application filed November 21h01,. Serial No. 80,882. (No model.)

To @ZZ whom it may concern: i

Be it known that l, WILLIAM J'.'S.rnone, aV

citizen of the United States, and af resident of the city of New York, borough ofglfrook-v lyn, in the county of Kings and State of'New York, have invented a new and YImproved Valve Mechanism for Goin-Controlled"Gras-y Vending Machines, of which the following is a full, clear, and exact description.` L The invention relates to coincontrolled gasvending machines; and its object is to pro'lJ vide a new and improved valve mechanism which is simple and durable in construction, automatic in operation, and arranged to prevent tampering therewith and consequent unlawful use of gas unless the proper coin is introduced into the coin mechanism.

The invention consists oi' novel features and parts and combinations of the same, as

provement as applied, part being broken out.- 1

Fig. 2 is a plan View of the sanne. Fig. "3is a transverse section of the same onthe line 3 3 of Fig. 4.' Fig. a is a sectionalside ele' vation of the same on the line 44 of/'Figfj The main shaft A of a eoincontrolled mechanism A of any approved construction'v is provided with a pointer B, indicating in' the usual manner on a dial O, and on the'said main shaft A is secured a cam D .for actuating an arm E on a rock-shaft F, journaled in a suitable stung-box G and extending into the gas-passage formed in a valve-body H, having oneend H threaded for connection with 4agas-supply pipe, the other end H'2 opening into a meter I. On the inner end of the rock-shaft F, within the gas-passage, is arranged anzarm J having a fork J engaging a pin or screw K, secured to a stem L, carrying a 'valve N, formed with two faces N and N2, of which the face l N is normally seated on a valve-seat O, and the other face N2 isadapted to be seated on a valve-seat P. The valve-seats 0 and P are formed with bearings O and P for the stem L to slide in,

and on? the said stern is coiled a spring Q,

resting with one end on the bearing P and pressing with the other end on the valve N,

so asK to hold the latter normallyT to its seat The valve-seats O and P and the bearings O' andP are secured on a cylindrical seat-body O2, fitting into the gas-passage, the outer end of the said body O2 having an eX lternal screw-thread screwing into the valvebody H, as plainly shown in Fig. 4. The bore of the body O2 is enlarged at its middle portion to allow the passage of the gas through the body at the time the valve N is in an open position. The double valve N, its stem N', and the seats O and P are all arranged in the single seat-body O2 to permit convenient removal of the parts for repairs whenever such are deemed necessary. The valve-stem L is lpref'rably arranged in a horizontal position, `andthe valve-seats O and l?, together with the valve N, are arranged in a horizontal portion of the gas-passage, as plainly illustrated in Fig. 4, the valve N being held to its seat O by the spring Q, as long as the pointer B is in the fzero positionthat is, as long as no coin has sured to the valve-body H by screws A5 A4, 9

screwing inside the casing through the back thereof into a portion of the valve-body H, so that when the apparatus is in use access cannot be had to the screws AB A4 unless the coin-controlled ,apparatusA is opened. If this is done by unauthorized persons, the owner of the vending apparatus at once detects that the apparatus has been tampered with. The back plate A2 is preferably provided with an angular flange A5, projecting in front of the cap H3 to prevent unscrewing ofthe cap H3 in case the offset H4 is tiled off ICQ by unauthorized persons. Access cannot be had to the valve mechanisml in the valvebodyH, and in case pressure is exerted against the face N' of the valve N the valve N will move from left to right and with the face N2 in contact with the seat l), so as to again close the gas-passage to prevent gas from flowing from the supply-pipe to the meter. It is expressly understood that when the valve N is moved in the regular way off its seat O by the action of the arm J on the pin K of the valve-stem L then gas flows from the supply-pipe through the gas-passage and the open valve to the meter and in an amount corresponding to that paid for by the coin introduced into the mechanism A.

The coin-controlled mechanism shown is of a well-known form, having a coin-barrel l, (shown in dotted lines and adapted to be turned byahandle 2,) the coin-barrel having a slot adapted to register with the coin-chute 3 in the casing. The inserted coin when the barrel is turned engages a pawl 4, pivoted on a spring pressed bar 5, and also engages a shoulder 6 on the bar, depressing the latter and holding the point of the pawl away from the toothed wheel 7 mounted on the shaft A. When the coin passes from the pawl and the shoulder of the bar, the pawl is rocked intoY position to engage the teeth of the wheel 7 and the bar is moved upward by its spring, causing the pawl to turn the wheel 7. A stud 8 engages the pawl just before the bar reaches the limit of its upward movement and withdraws the point of the pawl from the toothed wheel 7, and the toothed wheel is then gradually turned back by gearing operated by the meter to bring the pointer to the zero position. If two or more coins7 worth of gas is to be`purchased at a single time, the Y coins may be inserted one after another. When a quarter-dollar is dropped into the coin-chute and the handle is turned, then the pointer indicates at 25d on the dial, for two quarters at 50c., tc.

I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patentl. A valve mechanism for coin-controlled gas-vending machines, comprising a valvebody having a gas-passage and adapted for connection at one end with a gas-supply pipe and at the other end with a meter, the said valve-body being provided with two valveseats, a stem carrying a valve formed with two faces, the valve being located between the valve-seats, and the valve and valve-seats being in the gas-passage, the said valve-seats being formed with bearings for the stem to slide in, a spring coiled on the stem at one side of the valve and resting with one end on one of said bearings, the other end pressing on the valve to hold the same normally to its seat, a pin or screw secured to the other end of the valve-stem, a rock-shaft extending into the gas-passage, an arm arranged on the inner end of the 'rock-shaft within the gas-passage and having 'a fork at its free end engaging the said pin, and a coin-controlled mechanism for actuating the said arm to move the valve to open position against the tension of the spring, as set forth.
